污水处理厂对蛔虫卵的处理效果评价研究——以常州市为例

摘要

In order to understand the effect on treatment of Ascaris eggs of the city sewage treatment plant, this study uses the modified Bailenger method to detected concentration of Ascaries eggs with 5 sewage treatment plants in Changzhou.The results showed that:the influent water with sewage treatment plant mainly dealing with domestic sewage contain the highest concentration of Ascains eggs, Changzhou City, Wujin city sewage treatment plant.The average per liter of water contains 93.33 Ascains eggs;The influent water with sewage treatment plant mainly dealing with industrial area sewage contain the lowest concentration of Ascains eggs, Changzhou city sewage treatment plant in Qishuyan.The average per liter of water contains 13 Ascains eggs;The discharge water of 5 sewage treatment plant can reach the national standard of Ascaris eggs, The removal rate of Ascaris eggs up to 100％.%为了解城市污水处理厂对蛔虫卵的处理效果,利用改良的Bailenger方法,对常州市5家污水处理厂接纳污水和排放尾水蛔虫卵浓度进行检测.结果表明:以处理生活区污水为主污水处理厂接纳污水蛔虫卵含量最高,常州市武进城区污水处理厂,平均值93.33个/L;以处理工业区污水为主蛔虫卵含量最低,常州市戚墅堰污水处理厂,平均值13个/L;5家污水处理厂排放尾水蛔虫卵数量均能达到国家标准,蛔虫卵去除率基本可达100％.
